Garage floor paint - proper one not the MH's

I have recently extended / modified my garage so that I can park the van undercover. I am waiting a couple of months for the new concrete to dry out and was then thinking of painting with an epoxy paint to lock in the dust.

It's to late with this floor but when you build your new one get the builder to polish the partly dried concrete with a mechanical float, you can hire them from most hire shops looks like a small hovercraft, floor dries like glass afterwards with no dusting.
